She stepped in as interim DNC chairwoman following Rep. Debbie Wasserman Schultz’s (D-Fla.) resignation in July 2016 after hacked internal emails revealed that the party committee helped Clinton at the expense of Sanders and other primary rivals.

“There should be reforms. The primary process should be open and the strongest survive,” he said.

“Where I come from in West Virginia, no one has control over the primary process until the primary is over. Then that person comes in and selects their own chair for the party. That’s the way things are done,” Manchin added.

“I’ll be the first to admit that we have to earn the trust of everybody,” Perez told “The Thom Hartmann Program.” “And I’ll be the first to admit that the DNC didn’t put its best foot forward in 2016, and because of that we have trust gaps.”

Only 37 percent of Americans have a positive opinion of Democrats, compared to 44 percent who viewed the party favorably earlier this year, according to a new CNN poll conducted by SSRS, an independent research company.

Suspicions that the party establishment tilted the playing field in favor of Clinton during the primary disillusioned many Sanders supporters and may have depressed turnout in the general election, Democratic strategists believe.

Then-candidate Donald Trump sought to exploit the divisions by repeatedly accusing Democratic leaders of rigging the primary against Sanders — a charge he’s revived in the wake of Brazile’s book.

The DNC scheduled televised debates between Clinton and Sanders during odd times that weren’t likely to draw big audiences and froze the Sanders campaign’s access to a key voter database before the Iowa caucuses and New Hampshire primary.

Still, Brazile has taken criticism from Democrats, with some saying she has exaggerated the extent to which the DNC helped Clinton.

One senior Democratic senator expressed shock over Brazile’s broadside against Clinton, who remains beloved in the party.

“I have a hard time figuring out why she did this,” said the lawmaker, who requested anonymity to discuss internal party squabbles candidly. “I don’t for the life of me understand, unless there was some kind of personal slight.”

The senator noted that Clinton gave $20 million to the DNC to help pull it out of debt.

When asked about the need for reform, she said those discussion are “occurring.”

“I’m fully confident that we’re going to look at the mistakes that were made, the positive things and negative things, both that occurred in that election, and we will do what we need to do to go forward,” she said.

Even some of Clinton’s strongest supporters say they’re open to doing away with superdelegates and embracing other rule changes.

Murphy said he also favors doing away with presidential primary caucuses, in which liberal activists have historically had the most sway. Sanders was more successful in caucuses than he was in primaries last year.
